mmmmm.... idk why people rate an OS for its interface... i've tried Ubuntu a to get something to install its a big pain in the butt, you have to go thru a tut to install beryl, I dont think people can figure it out by themself.... and to install an app its even worst.. i really didnt find a use for ubuntu so i uninstalled it.
And for vista.. I have it on my spare HDD and use it just to tryout the DX10 games to see if they have huge difference which they dont.. other than that i dont use vista a lot.
anything that microsoft makes is shit ubuntu is coming 2 take over the world just wait microsoft stuff eva ave some glish or freeezin and it security is very bad hackers fine every way 2 go aroun d microsoft to run 2 ubuntu u need 2 ave a good graphic card and it nuh need lot a memory like vista and xp
